Devil's Number Review

Last Update: 20.06.2020. Author: SlotCatalog.

Devil’s Number is a gothic and spooky slot from Red Tiger Gaming, and it was launched 11 April 2019. It comes with 5 reels, 4 rows and 30 ways to win, and you’ll benefit from 2 different features in the base game. These are also active in the free spins feature, and you can win up to £100,000 on this highly volatile game.

Devil's Number RTP, variance & technical data

Devil's Number comes with an average RTP of 95.05%, and this is a high variance slot scoring 5 out of 5 possible points on Red Tiger’s own volatility scale. This means you can expect some dry spells here, and you need to adjust your bet level according to your bankroll while you wait for those big wins.

Devil's Number Review

Devil's Number is not your usual “run of the mill” video slot, and that’s due both to the theme and the mechanics. Red Tiger Gaming has really created something unlike themselves here, and on the flip side that usually means the result will not be for everyone. If cartoon style satanic spookiness is not your thing, then this is probably not the game for you.

The reels are set in a creepy old library at night, and the soundtrack adds to the ghostly atmosphere. If you’re planning an exorcism or an Ouija board session, Devil's Number slot would be the perfect warm up. It comes with 2 different features that can boost your winnings, and you’ll benefit from both of them in the free spins feature also.

Devil's Number symbols

Devil's Number slot comes with 9 different symbols, including the 5 standard low value card suit symbols. This leaves us with 4 high value symbols, and you need to get 3 to 5 identical symbols on a payline to win:

  • Magic Potion - gives you 12x for 5 on payline
  • Witches Brew Cauldron - pays 6x for 5 on a payline
  • Book of spells - pays 5x for 5 on a payline
  • Scrolls - pays 4x for 5 on a payline
  • 5 Card Suit symbols - pays between 2x and 1.2x

Devil's Number bonus features

Devil's Number comes with some nice bonus features, and you’ll benefit from 2 of them in the base game. These are features that will boost your wins, and we’re pretty sure you’ll welcome them with open arms.

Upgrade feature

As long as you win with with one of the 4 high value symbols, the Upgrade feature can come into play at random times. This feature will quite simply boost your winnings. If you land a winning combo with 5 Magic Potion symbols, for example, your winnings will be boosted up from the regular 12x to 22.2x.

Remove feature

Whenever you land a winning combo from the low paying card suit symbols, you can receive and extra chance if this feature is triggered. All the low value winning symbols will be removed from the reels, and be replaced by new symbols which gives you a new chance to win big.

Devil's Number free spins

The free spins feature on Devil's Number slot is activated when you land 3 of the 9 symbol on the 3 middle reels at the same time. The symbols are then turned upside down to reveal, you guessed it, the Devil's Number; 666 (spooky!).

After that whole seance is finished, you’ll be rewarded with 12 free spins, and both of the base game features will benefit you throughout the free spins feature. Any win from a low status symbol will remove these symbols for the duration of the feature, and every win from a high status symbol will upgrade the value permanently also. You can even re-trigger the free spins feature by landing 3 or more scatters.

Devil's Number jackpot (max win)

There is no progressive jackpot to be won on Devil's Number, but you can still win some pretty decent sums here. The max win is 2,500 times your stake, and this amounts to £100,000 if you play with the max bet of £40. An okay potential for a high volatility slot, but nothing extraordinary.

Devil's Number mobile & tablet

You can play Devil's Number slot on any mobile or tablet device you desire, and this game looks good on all handheld devices. Bring this spooky game with you wherever you want, and play under the quilt with a flashlight to set the mood. You can play on your iPhone and iPad, or you can play on your Android device.

SlotCatalog verdict

Devil’s Number is a charismatic slot you’ll either love or hate, and the base game comes with 2 different features that can help boost your winnings or give you another chance to win more. Of course, in the free spins feature you can benefit from both in a more permanent way. The potential could have been even higher, but we suspect people will be drawn to this game for the theme, more than the mechanics and the max win.


  • 2 win boosting features in the base game
  • Mark of the Beast free spins with both boosters active
  • Win up to 2,500x your stake


  • Theme is not for everyone
  • Potential could have been higher

Devil's Number SlotRank Calculation

SlotRank - is the rank of the game popularity in the specific market. We are calculating SlotRank based on the gathered data from the online casinos. Daily our crawling system scans thousands of casino sites. From each casino sites we are getting list of games, lobbies screenshot, and list of games in the lobby. Important parameter of games popularity is average games position in the casinos lobby. To calculate Average position in the casinos lobby (APL) for Devil's Number, we are using formula:

APL i = (105i + (287i - 1i) * 151 i) / 287i = 150.84

287 - quantity of valuable casinos with high weight in the United Kingdom. (Each casino gets weight. Casino weight is relevant to estimation of Internet traffic)
105 - Summa of positions in the casinos lobby
1 - Quantity of casinos that put game into the lobby
151 - We put size of casino lobby as 150 games. 151 - means that game is not in the lobby.

For the SlotRank calculation we are using SlotRank Value (SRV) parameter. SRV is sum of points that game gets for positions in the casinos lobby + points for presence in casinos + very minor value for game release date.

SRV i = 754.880i + (13.198 / 5000)i + ((0.1 * 17997)i / (5000 * 36500)i) = 4.603

SlotRank - is position in the game list sorted by SlotRank Value. Points that Devil's Number gets for positioning in lobby:
754.880 = SUM ((151- Lobby Position)* CRV)
CRV (Casino Rank Value). CRV - is casino weight coefficient from 0.1 to 1 that gets each casino according to their traffic estimation.
Lobby Position - position in the casino lobby. We are measuring position for TOP 150 games. Highest position means that game placed on top left position in the casino lobby.
